FAA orders replacement of PW1100G low-pressure turbine blades

[Ref 3-9 Dec Flight International Magazine]

A new airworthiness directive issued by Federal Aviation Administration (FAA), the US safety regulators, saying that airlines are required to replace low-pressure turbine (LPT) blades on some Pratt & Whitney PW1100G engines within 90, 180, 270 or 360 days, depending on the serial number. Notes : The FAA puts the cost of blade replacement at $785,000 per engine.

The move comes in response to more than 40 failures of the blades on PW1100Gs, which power Airbus A320neo-family aircraft, since 2017.  Rightly, those incidents have prompted regulatory action by other agencies, including India’s civil aviation authority.
